(54)	Method of successively manufacturing slender square conductive wires

(57) A method of manufacturing a square conductive wire which has a square-shape with four equal sides in section, comprises the steps of: preparing a conductive material sheet having a thickness T equal to the length of each the sides of the square-shape and a front and a rear surface 3, 4 which are in parallel to each other; and cutting the conductive material sheet at intervals each being equal to the length of the each the sides by a prescribed length in a direction orthogonal to the front and the rear surface. In this manner, small-sized square conductive wires can be manufactured successively.
